3 Claims. (Cl. 312-39) This invention relates to dispensing machines andmore particularly relates to a dispensing machine adapted for dispensingsheet material from rolls.

The object of the invention is to provide a holder for holding a roll ofsheet material within a dispensing machine housing in such manner that,the material can be grasped from the outside of the housing, unrolledfrom the roll within the housing and torn off to provide a sheet orstrip of the desired length.

A further object of the invention is to provide a dispensing housing forreceiving a plurality of rolls so that different kinds of sheet materialin roll form may be carried therein, such as foil paper, wax paper, orother types of paper commonly used.

Generally the invention comprises a dispensing housing within which tworollers are provided between which the web of sheet material is fed asit is unwound from the roll and passes out of the housing. One of theserollers is operated by a hand wheel and has a roughened surface thatwill cause even a web of the smoothest sheet material to frictionally,nonslippingly engage between the rollers for moving the web out of thehousing or cabinet through an opening in the front thereof.

The novel features that are considered characteristic of the inventionare set forth with particularity in the appended claims. The inventionitself, however, both as to its organization and its method ofoperation, together with additional objects and advantages thereof, willbest be understood from the following description of a specificembodiment when read in connection with the accompanying drawings,wherein like reference characters indicate like parts through theseveral figures and in which:

Figure 1 is a perspective view of the dispensing machine for vendingwebs of sheet material from more than one roll.

Figure 2 is a plan sectional view, taken on line 22 of Figure 1,illustrating how the roll of sheet material is housed within the housingof the machine, parts being shown broken away for convenience ofillustration.

Figure 3 is a fragmentary end sectional view of the dispensing machine,taken on line 3-3 of Figure 2.

Figure 4 is a perspective view of the roll holder re moved from thedispensing machine housing.

Figure 5 is a detail of the feeding roller, parts broken away forconvenience of illustration.

Referring specifically to the drawings, the new and improved dispensingmachine comprises a housing or cabinet 1, having a lid 2 hingedlymounted thereon at 3. Located within the housing are paper roll holders4. Each holder 4 comprises a back wall 5 which is rolled under at 6,coming up in front to rolled front edge 7 forming a trough in which aroll of sheet material seats. End walls 8 and 9 close the ends of thetrough and extend above edge 7.

A web feeding roller 10 is journalled between the ends 8 and 9 of theholder 4 above and forwardly of the from edge 7 of the trough. Thisroller has extensions or 2,824,774 Patented Feb. 25, 1958 EQQ spindles11 extending on either end adapted to drop down into the bottom of slots12, which slots open through the upper edges of end walls 8 and 9 andextend downwardly and rearwardly therefrom, as best illustrated inFigure 3.

A cover or sleeve 13 having a roughened surface surrounds the core 14 ofthe roller 10 which frictionally grips the surface of the web of sheetmaterial when revolved by the operator dispensing the sheet material,which may be wax paper or the like, out of the housing. The roller 10 isrevolved by the hand wheel 16 keyed on the spindle 11 at one end of theroller, a portion of the periphery of the wheel extending out through aslot 17 in the front 19 of the housing 1.

Transverse slots 18 extend across the front 19 of the a cabinet whichpermits the web 20 of the roll of sheet material 21 to pass through, asbest illustrated in Figures 1, 2 and 3. r

A transversely extending hold down or pressure roller 22 extendingbetween the ends 8 and 9 of the trough has spindles 23 extending beyondeach end and adapted to drop down into the slots 12 of the roll holder 4so that the hold down roller rests on top of feed roller 10. This holdsthe web 20 unwound from the roll 21 tightly down against the roughenedsurface 13 of the roller 10 so that when the roller 10 is revolved itwill pull the paper off the roll and extend it out through the slot 18.The upper edge of the slot 18 is serrated at 24 so that the paper can betorn off easily into sheets of any desired length.

The back wall of each roll holder 4 is fixedly secured at 25 to the back26 of the housing 1, as best illustrated in Figures 2 and 3.

Although a certain specific embodiment of the invention has been shownand described, it is obvious that many modifications thereof arepossible. The invention, therefore, is not to be restricted exceptinsofar as is necessitated by the prior art and by the spirit of theappended claims.

What I claim is:

1. In a dispensing machine for a roll of sheet material, a holdercomprising a trough shaped member for loosely retaining a roll of sheetmaterial and having upstanding side walls extending above and forwardlybeyond the front edge of the trough, said side walls having downwardlyand rearwardly extending slots opening at their upper ends through thetop edges thereof, a dispensing roller having the ends thereof journaledin said slots and being disposed above and forwardly of the front edgeof said trough, said dispensing roller having a roughened cylindricalsurface for frictionally engaging the web of a roll of sheet materialand unwinding the same from a roll of sheet material disposed in saidtrough as the roller is rotated, and a hold down roller journaled insaid slots and gravitationally bearing against said dispensing rollerfor maintaining the web of a roll of sheet material to be dispensed incontact with the roughened surface of said dispensing roller.

2. A dispensing machine comprising a housing having front, back, top andbottom walls, said front wall having at least one dispensing slotextending thereacross for dispensing a web of sheet material from thehousing, at least one holder within said housing, said holder comprisinga trough shaped member for loosely retaining a roll of sheet materialand having upstanding side walls extending above and forwardly beyondthe front edge of the trough, said side walls having downwardly andrearwardly extending slots opening at their upper ends through the topedges thereof, a dispensing roller having the ends thereof juornaled insaid slots and being disposed above and forwardly of the front edge ofsaid trough, said dispensing roller havingaroughened cylindrical surfacefor thereof'journald in said slots and being disposedab'ove andforwardly of the front edgefof said ,troughrisaid dispensing rollerhaving a roughened cylindrical surface for V frictionallyengaging theweli of a roll of sheet material a roll r-ofwsheet material to'bedispensedjnicontact,with V the roughened surface'oftsaiddispensingroller; said'rollers being disposed adjacent'said dispensingslot, and means for rotatingsaid dispensing roller comprisinga'hand'wheel keyed to said dispensing of's aid' housing. t
